Question

我正在尝试反序列化Silverlight客户端中的一些JSON对象，这些对象通过SignalR发送到客户端。

使用TypeNameHandling = TypeNameHandling.All设置序列化了这些对象。

第一个问题是您无法将类库项目引用添加到Silverlight项目中，因此我使用了创建包含指向POCO类的链接的Silverlight类库的技巧。

但是反序列化时出现错误，因为JSON字符串包含完整类型，包括程序集（不同）。如果我操纵JSON字符串并替换程序集名称，仍会得到相同的错误。

这些是POCO：

public abstract class MessageBase
{
    public Exception Exception { get; set; }
}    

public class AccessRCImported : MessageBase
{
    public DateTime Cob { get; set; }
}

这是JSON字符串：

{"$type":"CS.RAR.ICE.Common.Messages.AccessRCImported, CS.RAR.ICE","Cob":"2012-08-01T00:00:00","Exception":null}

已由

序列化

var output = JsonConvert.SerializeObject(message,
                                                 new JsonSerializerSettings
                                                     {TypeNameHandling = TypeNameHandling.All});
// Replace the assembly name
var result = output.Replace(", CS.RAR.ICE.Common", ", CS.RAR.ICE");
var ctx = ConnectionManager.GetHubContext<ServerHub>();
ctx.Clients.Notify(result);

然后在Silverlight客户端上，我正在做

var message = JsonConvert.DeserializeObject< MessageBase>(onData, _serializerSettings);

我得到以下错误。 Silverlight应用程序和Silverlight客户端库都针对Silverlight 5。

有什么想法吗？

感谢。

将JSON对象反序列化为Silverlight中的POCO对象
